Overall yes, much of the sun's volume is gaseous material which is much lighter than the rock and metal that the earth is composed of.
The density of Earth is 5.56 g/cm3 whereas the sun is 1.4 g/cm3 the earth is the most dense object in our Solar System (as far as we know)
Basically, it is further from the sun, it is smaller and its atmosphere is far less dense.
Earth is more dense.
Venus has sun rays that are seven times stronger than Earth's due to its dense atmosphere that traps heat and creates a greenhouse effect.
It depends on what part of the sun you sample. On average, yes. The average density of the sun is about 1.4 times the density of water, more than 1,000 times denser than air. The outermost part of the sun is far lass dense than air while the core is far denser than even the densest substances on Earth.
The earth is smaller, cooler, greener, wetter, less massive, and more dense than the sun. It emits less electromagnetic radiation, and rotates on its axis 30 times as fast as the sun.
Both are rocky. Both are dense, but Earth is far more dense than the moon is.
It is neither. The densest layer is the inner core. The least dense layer is the crust.
No, the Sun is older than the Earth.
The sun's mass is about 333,000 or about one third of a million times that of Earth, but the sun's volume is about 1.3 million times that of Earth. In other words, the sun is less dense than Earth. Mass is a measure of how much matter is in an object, not its size.
less dense than the material of the Earth's mantle
No, Venus is closer to the Sun than the Earth.
Yes. There is a bit of debate concerning the density of our local star, but a figure of about 1.4 grams per millilitre is good. The density of water, as you probably know, is 1 g/ml, so the sun is about 1.4 times as dense as water. The density of the sun will vary, and it is going to be more dense in the core than farther from its center, and you probably guessed that, too.
